Perpetuals on Robinhood Chain: What They Are For

Everything else on this chain is a long. You buy a token, a stock token, an LP position, and each of them pays when something goes up. Perpetuals are the exception, and that single property is why they matter more than the leverage they are known for.

What is available

Lighter is a ZK-powered perpetuals DEX native to the chain, running orderbook-style rather than AMM pricing, covering crypto and index markets. Arcus is a stock-token and crypto DEX from dYdX Labs and Robinhood Crypto with pTokens and cross-market trading.

The distinction that matters between them is what you can express: crypto direction on one, and positions that reach across stock tokens and crypto on the other.

The two things a perp gives you

Direction is the important one. Without a short, a view that something is overvalued can only be expressed by not owning it, which pays nothing. With one, the view has a position attached.

Leverage is the famous one and the less useful. It does not improve a trade – it multiplies both sides of it, including the part where you are early rather than wrong.

The two costs

Funding is paid continuously by whichever side is crowded. Holding a popular position through a quiet market bleeds regardless of price, which is why perps suit views with a timeframe and suit buy-and-hold not at all.

Liquidation is the other. It closes your position at a price, not at a conclusion. Being right about a company or a token and liquidated on the way there is the most common expensive outcome in this instrument, and it is entirely a sizing failure.

Sizing, which is the whole skill

1. Start from the liquidation price, not from the position size. Decide how far the market may move against you before you are wrong, then size so liquidation sits beyond it.
2. Assume the worst path, not the average one. Volatility on this chain is memecoin volatility even in majors.
3. Treat funding as a rent bill. If the thesis needs three weeks, calculate what three weeks of funding costs before entering.
4. Never use maximum leverage because it is offered. The maximum is a product feature, not a recommendation.
5. For a hedge, size against the position being hedged rather than against the account – a hedge scaled to the portfolio usually becomes a second directional bet.

Who should not touch these

Anyone using them to recover a loss, anyone who cannot state the liquidation price of a position they hold, and anyone whose reason for leverage is that the account is too small. That last one is the most common and the most expensive: leverage does not solve insufficient capital, it converts it into a faster ending.

Used narrowly – to short something specific, or to hedge a position you actually hold – perps are the most useful instrument on the chain. Used to make a small account behave like a large one, they are the fastest route to not having an account.
